Bonjour,je dois exprimer chaque aire en ares,puis en hectares. a.47,504 dam2 b.47220 cm2 c.0,00588 km2 d.17500dam2 e.47,5 hm2 f.914000 dm2 Merci d'avoir lut cet

1 are = 1 dam² et 1 hectare = 100 dam² = 1 hm²
a. 47,504 dam² = 47,504 ares = 0,47504 hectare
b. 47220 cm² = 0,047220 dam² = 0,047220 are = 0,00047220 hectare
c. 0,00588 km² = 58,8 dam² = 58,8 ares = 0,588 hectare
d. 17500 dam² = 17500 ares = 175 hectares
e. 47,5 hm² = 4750 dam² = 4750 ares = 47,5 hectares
f. 914000 dm² = 91,4 dam² = 91,4 ares = 0,914 hectares
